Patented Nov. 29, 1932 i UNITED STATES PATENT OFFICE COLORADO, AssIGNOR-OE ONE-FOURTH To D. V.TR1BBY, OF DENVER, COLORADO TOOL i' 'Appncafion filed Maren 3o, 1931. semi No. 526,397.

My invention relates to a combination tool. The principal Object is to combine in a single toolva plurality of tools. Another object of the invention is to provide Vmeans for adjusting jaws, comprised in theinventiom rela.- tive to each other. Y

A further Object is to providemeans for holding handles ofthe tool in a locked posi'- tion.

Still other obj ects reside in novel details of construction, and in novel combinations and arrangements of parts, which will appear in the course of the followinfg description.

In the drawing, like re erence characters designate similar parts inthe several views.

Figure 1 is a side view of a combination tool embodying the features of my invention.

Figure 2 is a section taken on the line 2 2 of Figure 1. l

Figure 3 is a section taken on the line 3 3 of Figure 2.

Figure 4 is a section taken on the line 4 4 of Figure 1.

Figure 5 is a section taken on the line 5 5 of Figure 1.

Figure 6 is a detail view of one of the jaws comprised in the invention, taken on the line 6 6 of Figure 1.

Referring more in detail to the drawing, the reference characters 6 and 7 designate jaws having toothed, adjacent faces. The jaws have complementary angularly disposed grooves 39 for removing cotter keys and the like. The jaws have notches for cutting wire. The notch in jaw 7 is shown at 8. The corresponding notch in jaw 6 lis not shown. Handles 9 and 10 of the tool respectively control the jaws 6 and 7.

At the end of the handle 9, opposite to the jaw 6, is a. screw driver 11. At the adjacent end of handle 10 is an adjustable wrench 12; since it is of conventional design, a detailed description appears unnecessary.

rIhe screw driver carries a wire loop 13, which is pivotally mounted in the sides of the screw driver and fits in a groove 14 in the shank of the screw driver. When it is desired to hold the handles together, the loop 13 is moved from the groove and slipped around the end of a fixed jaw 15 on the wrench 12, as shown in dotted lines Figure 1.

The handles are bowed at 16 and 17 and internally serrated to provide a wrench for automobile hub caps, pipes, and the like. Since the handles are movable, this latter WrenchV is adjustable. The handles also have on opposed faces complementary grooves 18 of graduated size, adapted to beused as Wire connectors.: One pair of complementary grooves"19 are composite in nature. The groove 19 is angular throughout. At one end 20, the bottoms of the grooves are parallelcWith each other. At the other end 21,.the bottoms of the grooves are convergent. The end20 is suitable for holding a tap, and the end'21 is-suitable for holding an auger bit.

A stop-member for the handles is also provided to limit-the distance at which they may be' moved apart. The handle 10 has a threaded aperture 22, infwhich is screwed an internally and externallyfthreaded sleeve 23 provided with a knurled head 24. The handle 9 has a smooth slot 25 alined with the threaded aperture 22 of the other handle. The slot is relatively long and tapering, as shown in dotted lines l25a in Figure 1. A bolt 26, eX-v tending through the slot, is secrewed into the sleeve 23. The bolt carries a winged head 27 on an angular end 28. Y Y j i The tool likewise has a laterally adjustable pivot'. VThe handle 10 has an enlarged head 29 provided with a plurality of rounded recesses 30 disposed at opposite sides and at opposite ends of a slot 31. An angular pin 32 extends through the handle 9 and through the slot 31 of the handle 10, and can be `turned relative to both handles. A washer 33 has an angular opening, thesame shape as a cross section of the pin, wherein the pin fits to cause rotation of both the pin and the Washer when either is rotated. The washer is held on the pin 32 by a cotter key 34. The washerhas rounded det'ents 35, which iit in the recesses 30. The washer 33 is preferably of spring metaland forced tightly against the head 29,

whereby the detents 35 are compelled to spring into the recesses 30 when in register therewith. 'y j The pin 32 is oblong in cross section, as

shown in Figure 3. The length of the cross section is greater than the width of necks 36 connecting enlargements 37 of the slot 31. Therefore, when the pin is in the full line position shown in Figure 3, it cannot be moved to another position in the slot 31, but locks the handles in position.

In the use of the tool, when it is desired to change the relative positions of the handles, the pin 32 is manually turned and the pin is then moved through either of the necks 36 in the manner shown in broken lines in Figure 3. When the pin has been moved past the neck of the slot, it is turned crossways in the slot and is thereby held in one of the enlargements 37 by the engagement of the detents in corresponding recesses. When the washer and pin are turned to dierent positions, the detents are forced out of the recesses, by the resiliency of the washer and are moved into different recesses.

The gripping faces of the jaws 6 and 7 are parallel in one position. As the pin is moved to diderent parts of the slot 31, the jaws 6 and 7 may be moved to diierent distances apart. When moved together, the jaws 6 and 7 present a long nose that is easily inserted in small spaces, which is a valuable feature of the present tool. rlhe broken lines in Figure 1 show the positions of the handles and jaws, when the latter are together.

The threaded sleeve 23 and the bolt 26 furnish what might be termed an extension bolt. When it is desired to have the handles relatively far apart, as when the bowed portions 16 and 17 are being used as a hub cap wrench, the bolt is partially unscrewed from the sleeve 23 and the latter is screwed into the handle 10. Vhen a shorter connection is desired, the bolt 26 is screwed into the sleeve 23, while the latter is partially unscrewed.

When the tool is gripping an object, the handles may be locked in position by screwing the head 27 tight against the side of the handle 9, with or without screwing the sleeve 23. The slot 25 allows movement of the handle 9 around the pivot pin 32 without restriction by bolt 26. Moreover, the sides of the slot 25 do not rub and wear off the threads of the bolt 26, which has been an objectionable feature of other locking pliers.

It is to be understood that changes may be made in the details of construction and in the arrangement of parts, without departing from the spirit of the invention.

It is to be understood that during the use of the tool the pin 32 turns with the head 29, through the intermediary of the locking washer 33. By reason of this construction, the pin does not turn in the slot 31 during use, which eliminates the greatest source of wear. The pin turns in the handle 9 during use, but since the pin its closely in the latter handle, there is no play, and wear is reduced to a minimum.

What I claim:

1. A tool comprising pivoted handles, stop means for the handles comprising a member having a threaded connection with one handle, and a bolt having a threaded connection with said member and limiting the movement of the other handle.

2. A tool comprising pivoted handles, one handle having a threaded opening, a sleeve having internal and external threads, the latter engaging the threads of said opening, and a stop bolt having a threaded connection with the internal threads of the sleeve and limiting movement of the other handle.

3. A too'l comprising pivotal handles respectively having a substantially smooth slot, and a threaded opening opposite thereto, an eXteriorly and interiorly threaded sleeve screwed in the threaded opening of the one handle, and a headed stop-bolt passed through the slot of the other handle, and engaging the interior thread of the sleeve, the last-mentioned handle being limited in movement by the head of the bolt.

In testimony whereof I hereunto affix my signature.

GEORGE W. LANE.
